overclocking dhd

I have recently rooted my dhd and currently running CM7. Using the cpu setting within the performance menu I am wondering what peoples thoughts are on a noticeable but safe increase of cpu speed. its set as 1017MHz which i believe is default. I am told I can run anything up to 1500 safely. can anyone confirm this and also tell me what kind of result (performance and battery life) i should expect.
thanks

Well, I use Android Revolution HD (a sense rom, meaning heavy UI!) and i overclock to about 1.3GHz. In terms of battery life when it's awake, it seems a drain a teeny bit more readily, but I've never had a freeze on sense (quite rare)
On stock it underclocks to let the processor max at around 400MHz when the screens off, so that helps to really save a lot of battery on standby. On CM, I'd expect it'd feel more or less the same in terms of performance after you hit 1.2/1.3GHz

thanks for the reply mate. going to try out revolution HD soon i think. have you overclocked using a third party app or is there one built into that rom?
also im a little confused by the governors. 'on demand' is the default governor. Does that mean it will only use the max selected cpu speed when necessary? would you recommend using a difference setting?
cheers

The CPU is managed by the ROM itself. You can tweak it yourself by using setCPU (or similar), but I can advise you not to. Can't help you with the governors buddy, since I dunno what it is

Lucky you picked a linuxhead!
The system itself has a daemon (background process built into the system) that handles overclocking. It's all explained on the page and also on this thread:
http://forum.xda-developers.com/showpost.php?p=14638641&postcount=34279
You can use another app (like SetCPU) but the daemon usually handles screen off's quicker. The governors basically determine how the processor frequency is changed. I'll explain the common ones:
Performance - Runs at highest speed, so if you have a range of 200 to 1.3G, it'll stay at 1.3G all the time, not usually the best
Ondemand - The universal default for phone overclocking, it only changes the speed up after a certain percentage of the CPU is used, and it switches on the fly, so if the CPU is used too much at 400MHz, it'll ramp it up to maybe 600 or 800, and if it's still overused, it'll put it up to maybe 1 or 1.2G
Conservative - This is like ondemand, except it makes the changes more gradual. It can give noticable lags in the foreground at times, so this is mainly used when the phone is asleep (screen off)
Smartass - This governor is like ondemand, except it'll less readily switch frequencies to higher values when it detects the screen off. This isn't really used because the overclocking daemons take into account the phone being awake or not
Basically, there isn't really a need to change governors, only really frequencies if anything. The thread, however, does tell you how to change governors.

Im using latest LeeDroid GB 3.2.1 and to be honest with the work he's done with the Kernal (3.1.8BFS) I have found that the ROM is a lot MORE responsive without me overclocking the CPU.
Im not really sure how it all works, but I guess doing this on different ROMS has its own different out comes.

overclocking has me confused too, is there really that much of a benefit in it? how much will i gain from it?

There is a benefit when you use certain apps, or even sense itself. For example, I've never had sense ui freeze, or go slow. The under clocking helps to improve the rubbish battery life when your phone is asleep.
In terms of measuring the gain, I have no idea. Really, I'd think you could use a process heavy app, or benchmarking app and see.
There's also loads of guides on overclocking to help out! (that's how I got the hang of it! )

For the need on OC, it depends on the kind of apps u're using. If u're happy w a non OC DHD, its totally up to u.
But for the UC, it works as a terrific battery saver, mich better/effective than other battery saver soln on market

The safe range depends on the DHD as the manufacturing changed even though same part, i'm OC 1.5GHz "On Demand" profile and under clock 245MHz on screen off "Power Save" profile.

Overclocking

apologies if this has been asked before. I'm using cm7 and have been looking at the performance settings. What value can I safely set for overclocking without shorting the life of my device
Sent from my HTC Desire using XDA Premium App

Without shortening. Its life is about 1113650
1.1 Ghz
Sent from my HTC Desire using XDA App

Try 1136000 first and see how it reacts on your phone, some phones will get warm with such settings.
My Desire for example can handle 1075000 without getting warmer compared to 998000 (normal) but with 1136000 it will get slightly warmer (warmer but no no signs of overheat even after playing heavy games).
I decided however to keep the 1075000 instead of 1136000.
BTW: I am on InsertCoin 1.0.9 + v06 kernel

On and off system lag. Is it related the amount of apps installed?

I am currently running mikG 2.45 more freedom. Titanium backup loaded 335 Apps, which include system apps. I am thinking the maybe 200+ apps I have installed are the reason for the on and off lag.
Sent from my PC36100 using Tapatalk

Apps maybe be paying apart in it but you say your running "more freedom" try running the stock freedom not the more or less or extreme or whatever he calls them. The undervolting may be limiting your processor. Also use set CPU and try to overclock a little. Im running synergy rls1 with stock freedom overclocked up to 1152 smooth as a whistle and battery is through the roof. try stock freedom and if that dont work pm me and ill help u out more if needed

Overclocking doesn't really show a noticeable impact in my experience. Only if you are playing a CPU intensive game that pins your CPU at 100% then it drains slightly faster not to bad tho. Also if you use the "interactive x" governor it manages the cpu's frequencys to try to keep them as low as possible so you only using enough to do a task instead of going 100% for something that doesn't need that much power. It also keep the CPU at the lowest frequency you allow it to be when you shut off the screen. So if you set your Max to 1152 and min to 245 for example. When you shut off the screen it will stay at 245 and not jump around. That tremendously helps battery. It about 8p.m. here and i have had ghis on since 7 a.m. and I'm at about 30% and that's with quite a few text, 2 - 5minute calls, about 20 minutes of games, and an hour of music. The only bad thing about overclocking is that if you go overclock to far for to long you can fry your phone. But ive been running 1152 for about 6 months and perfectly fine so i figure that's pretty good. If u have more questions or need help pm me
Edit: i forgot i also had about 20 min of internet/xda browsing on wifi and the past 45min on 3g doing the same thing haha

What is overclocking?is it harmful or ADVANTEGOUS?WHAT is its basic use?

Sent from my HTC Wildfire using XDA App

Overclocking is setting the processor speed higher than it is meant to go, if overclocked too far, it can be dangerous, but usually it improves the overall speed of the phone.
691MHz/710MHz are probably the best and safest Max speeds to go with, on my kernel I have 633MHz as default Max, but it can be overclocked higher to a very unstable 800MHz.

Sent from my HTC Wildfire using XDA App

Over clocking is good!
Over clocking can be harmful in the sense that it can make your device unstable if you over clock at a high speed, although there are benefits to over clocking such as increasing the speed on your android device to attempt to reduce things such as lag on low end devices such as the HTC Wildfire (Buzz).

Use Rom Toolbox (its downloadable from android market for free or donate)
Sent from my HTC Wildfire using XDA App

i have also underclocked my processor as well as overclocking it so that when the phone is idle, it uses less batteryto keep things going.
one bit of advise, dont just max things out. start low and increase the OC slightly, test for a day or day, if everything seems fine, raise the bar until things become unstable, like the launcher jumping or sceen transitions becoming glitchy then reduce by one stage and this will be your optimum OC speed.
My phone can OC to about 791MHz but i'm only set at 652MHz. And the stock UC was about 400MHz and i have reduced to 264MHz

(Q)I have a og evo and cant overclock it 1.2ghz.

I have a og evo I want to know why when I overclock to 1.2ghz it freezes my phone why does it do that ?
Sent from my Nocturnal 4G using xda premium

Each Evo is different. Some of them can't handle that high overclock, or can't be undervolted very low. Each one is different, each has its limits.
I don't understand the big deal with overclocking. It burns your battery faster. I personally underclock, with little to no lag and is good enough for my casual gaming needs

Mine doesn't like a clock much at all. I can get about 1.1 before it starts locking up but even then it hangs a lot. I honestly don't see a difference from 1.0 to 1.2. Get a decent rom, good kernel and try out the v6 script an I almost guarantee you will like that better.

Well for us to be able to help you, you would need to provide us with more details on how you are trying to accomplish this.

I use no frils cpu but have also tried setcpu and viperMOD I know that's the best way to overclock but is very confusing. Have any step by step instructions to of to 1.2 I know having higher voltages helps as well.

Overclocking is overrated. If you need to overclock for every day usage, then something is wrong - at least in my opinion. Resource intensive gaming is different, but you shouldn't need to overclock for browsing, texting, casual games, etc.
Try out the V6 Supercharger script. I'm not currently using it, but have in the past and it seemed to make my phone more snappy. A lot of people swear by it and it's a great script, definitely worth a shot. There are other things you can do to speed up your phone without overclocking. I'd try other options first since overclocking will chew through your battery. Increase the dalvik vm heap size, there are plenty of free apps on the market to help with this task. Uninstall apps you don't use, I'll bet that you never use some of the apps on your phone. Back them up with Titanium Backup and you can restore them if you ever need them again.
In case you didn't already know, the Evo can't overclock past 1.2, I'm not 100% sure why - it has something to do with the processor.

I never oc over 1075 and only when plugged in if i play a game I need to oc.for I just activate my charging profile and plug up and play 1.2 ghz is a good chance of doing serious.damage as these older scorpion processors get very very hot at that clock speed so they lock up to try and protect themselves from heat damage or they shut down the phone 1075 is as high as you should need to go for any games the evo can handle on the subpar gpu

I'm pretty sure viperMOD is more for undervolting than overclocking, which are not suppose to be combined together. I am running vipermod with max voltages - 50. Other nite was playing snes9x and was getting some lag with a game so I bumped max CPU up to 1.2. Phone went into a bootloop and had to superwipe and reflash everything. Don't know if its b/c vipermod + 1.2 CPU or just bumping up CPU. Didn't try it again.

Get a shift. Mine runs fine at 1.9. But usually run it art 254-1200 on demand.

You can overclock and undervolt together just fine. You just need to ensure that every frequency has a high enough voltage to run the processor at that step. My Evo is overclocked and undervolted just fine, although IIRC I can only push it up to 1.1 GHz . My tablet is 1ghz to 1.6ghz and is undervolted as well, though.

merge rls 2.0, iron monkey, Droid overclock because of the profiles options. I set up four profiles including one for temp. sometimes i'm underclocking and sometimes overclocking but only up to 1.19 to prevent freeze and boot loops. Only downside is right at open Droid overclock needs su permission but that is my choice since profile changes at open.
Very snappy afterwards.

When I had the 4G, I was never able to go above 1118, or somewhere around that. It would have freezing issues.
On my evo shift, I was able to do 1.7 gHz (compared to stock 800 mhz) ok. 1.6 pretty reliabily, and I could run 1.5 all day long. Some guys could do 1.9. It just depends on the phone.

Actually overclocking and undervolting is counter-productive. What you should do, is read carhaulers and ropodopes guide over at vaelepak. Its give some good useful info about how to set up a good aosp rom. I'm underclocked, undervolted, and still getting 1400+ benchmarks. Check it out bro. You'll love the results.

What? Overclocking and undervolting are two completely different things, and they aren't mutually exclusive. Unless you can provide a good reason as to why it's counter productive to do both, I don't buy that at all. Just checked my phone, my overclock requires an extra 25 mV for all three steps I've overclocked. 25mV isnt much, and it certainly isn't going to kill my battery that much faster.
Besides, the only time the CPU is going to be entering these high power modes is when it needs to do work, and it's better to do work as fast as possible to go back to sleep. Would you rather wake up, do a mundane task for 5 minutes, then go back to sleep or wake up, do a task at 2x the speed while only consuming 30-50% more energy, then going back to sleep after only 2.5 minutes?

First let me say I don't use viper mod or any voltage controlling mod.
On sense 3.0 roms such as mikg I over clock to 1152 and set the minimum to 384 and its smooth as butter. No problem and battery lasts all day.
On aosp however such as decks (I'm on it now) I underclock to 499 and leave the min at 254. Smooth as always and battery lasts forever.
Anything past 1152 is going to cause problems (at least in my experience) also the rom/kernel can effect how much you can overclock.

Its counter productive because it is giving less to something that needs more. (Don't take this post as me trying to be a ****. Just voicing how someone explained it to me a while ago)
Think of this as cars.
Lets say you have a nice fancy v8 mustang. Stock, everything is well, balanced.
If you start adding parts and get it pushing out 1000 horsepower (overclock) your most likely gonna need more feul (voltage) or at least stock amount flowing into the engine just to keep it running.
Now lets say you got that same 1000 horsepower gas destroying mustang and you start to lower the amount of gas flowing into the engine (undervolt (done in vipermod)) cylinders (CPU) wont get enough gas, it wont work, and your stuck going no where.
So if that made sense (did to me) then you can see why they are counter productive. Unless your using vipermod to overvolt (which idk if you can since I don't use it) then you can disregard this whole post

Your car analogy is completely irrelevant. You can look up the exact voltages that the CPU runs on at every frequency, *even when overclocking*. Overclocking an Evo 1ghz to 1.2ghz takes maybe a 5% bump in voltage, and that 5% extra power is only going to be used *when the CPU is running at max speed* (which is only when there is a lot of work to do), and even then, it's *still better to let the CPU run at max speed with a tiny bit more power consumption than to cap the CPU at a slower speed and make it work for even longer*. Intel calls it HUGI, Hurry Up and Get Idle.
I know what I'm talking about, and I wish people would stop trying to argue with me based off of second hand speculation. I do this for a living, after all. There is absolutely nothing wrong with overclocking and undervolting, and it's the best way to get the most battery life *and* performance out of your phone, period.

Hmm, *interesting*. I believe the best answer to the OP was covered rather well earlier. It's all about your rom/kernel/hardware combination. With all the variables to consider as relevant, your best bet is to experiment and find what works for your device. Don't check set on boot untill you are confident the set-up is stable. Higher is not always better with overclocking. My device runs blazingly well underclocked @768max. Gets insanely great battery @499max. However my quadrants are better @ 1036 than at 1190.
Great thing about android is you can experiment and learn through trial and error.
